Problem: Problem

Given the strings S and Q queries.
The i-th query (0 ≤ i ≤ Q-1) is given the closed interval [li, ri] and the string Mi. Output how many character strings Mi exist in the substring from the li character to the ri character of S.

Constraints

* 1 ≤ | S | ≤ 100000
* 1 ≤ Q ≤ 100000
* 1 ≤ | Mi | ≤ 100000 (0 ≤ i ≤ Q-1)
* 0 ≤ li ≤ ri <| S | (0 ≤ i ≤ Q-1)
* All characters are lowercase
* The total number of characters in string M does not exceed 2000000

Input

The input is given in the following format.


S Q
l0 r0 M0
l1 r1 M1
..
..
..
lQ−1 rQ−1 MQ−1


The string S and the number of queries Q are given on the first line, separated by blanks.
The following Q lines are given the integers li, ri, Mi, separated by blanks.

Output

The output consists of Q lines. Print the answer to each query on one line in turn.
